The impact of disorder on Dirac plasmon losses
arXiv:1307.7371 · doi:10.1103/PhysRevB.88.121405
Abstract
Recent scattering-type scanning near-field optical spectroscopy (s-SNOM) experiments on single-layer graphene have reported Dirac plasmon lifetimes that are substantially shorter than the dc transport scattering time τ_{tr}. We highlight that the plasmon lifetime is fundamentally different from τ_{tr} since it is controlled by the imaginary part of the current-current linear response function at finite momentum and frequency. We first present the minimal theory of the extrinsic lifetime of Dirac plasmons due to scattering against impurities. We then show that a very reasonable concentration of charged impurities yields a plasmon damping rate which is in good agreement with s-SNOM experimental results.
